CM102-A+/102S+ USB 2CH Audio Controller for Speaker DESCRIPTION CM102-A+/102S+ series is a highly integrated single chip for USB stereo speakers application. Minimum external components are needed for building an USB speaker system, which makes CM102-A+/102S+ a simple and very cost-effective solution. Since no driver is necessary for audio playback on all major OS. CM102-A+/102S+ provides a truly plug-and-play feature for external digital audio playback. For energy saving, USB suspend mode and resume is supported by CM102-A+/102S+. With power amplifier enable pin and volume control VR input pin, a traditional speaker front panel design can be built. This new single chip not only support 44.1KHz and 48KHz sampling rate playback but also with X2 modulation for hi-frequency quality.
